ECU117 carries out the control of PDU109, VCU107, common charger 103 and quick charger 105 and switches set 115 Open and close controlling.In addition, ECU117 derives high power capacity by way of electric current bulk billing system and/or OCV (open-circuit voltage) presumption Each capacitance of storage (SOC of type battery ES-E and high performance type battery ES-P：State of Charge, it is also referred to as " remaining Capacity ".) and be managed.
Next, illustrating to the difference of high capacity type battery ES-E and high performance type battery ES-P.
The characteristic of high capacity type battery ES-E is mutually different with the characteristic of high performance type battery ES-P.High capacity type stores , compared with high performance type battery ES-P, output weight density is low for battery ES-E, but energy-weight density is high.On the other hand, it is high , compared with high capacity type battery ES-E, energy-weight density is low for output type battery ES-P, but it is high to export weight density.This Sample, high capacity type battery ES-E are on this point of energy-weight density relatively excellent, and high performance type battery ES-P is in output On this point of weight density, is relatively excellent.It should be noted that energy-weight density refers to the amount of power (Wh/ of per unit weight Kg), export the electric power (W/kg) that weight density refers to per unit weight.
The excellent high capacity type battery ES-E of energy-weight density is the electric storage means with high power capacity as main purpose, in electricity All the time by constant electric power to 101 supply electric power of dynamotor during the traveling of motor-car.Therefore, high capacity type battery ES-E The desired value of SOC be set low, the SOC of high capacity type battery ES-E is along with traveling until reaching the desired value Till persistently reduce.On the other hand, it is the syllabus based on height output to export the excellent high performance type battery ES-P of weight density Electric storage means, when the traveling for electric vehicle is needed compared with large driving force, to 101 supply electric power of dynamotor.Separately Outward, the regenerated electric power that dynamotor 101 generates electricity and produces preferentially is input into high performance type battery ES-P.Therefore, height output The desired value of the SOC of type battery ES-P is set to the median higher than the desired value of the SOC of high capacity type battery ES-E, The SOC of high performance type battery ES-P is changed in the way of maintaining the desired value in its vicinity.It should be noted that dynamoelectric and power generation Although the regenerated electric power that machine 101 sends preferably is input into the SOC of high performance type battery ES-P as described above, cannot be to height The regenerated electric power amount that output type battery ES-P is charged can also be charged to high capacity type battery ES-E.
The different such as causes of the high capacity type battery ES-E of described above and the characteristic of high performance type battery ES-P In the various parameters determined by electrode, active material, the structure of the inscape of battery, material etc. as electrolyte/liquid. For example, for as represent can discharge and recharge electricity total amount parameter accumulation capacity for, high capacity type battery ES-E It is more excellent than high performance type battery ES-P.On the other hand, for as represent accumulation capacity relative to discharge and recharge resistant to deterioration For charge rate (C-rate) characteristic of the parameter of property, high performance type battery ES-P is more excellent than high capacity type battery ES-E. In addition, for as represent for the internal resistance (impedance) of the parameter of the resistance value of discharge and recharge, high capacity type electric power storage Pond ES-E is higher than high performance type battery ES-P.Therefore, the charging of high capacity type battery ES-E is poor by characteristic.
So, it is different from characteristic in high performance type battery ES-P in high capacity type battery ES-E, according to the characteristic Different and caloric value of in each battery is also different.Fig. 2 is to represent high capacity type battery ES-E and height output in graphical form The different figure of the characteristic of type battery ES-P etc..As shown in Fig. 2 in high capacity type battery ES-E and high performance type battery In ES-P, voltage, energy-weight density, output weight density, charging are carried out by characteristic, internal resistance, using external power source The charger that mainly uses during charging, the desired value of SOC, regenerated electric power receive that benchmark is different, and the difference is to the big of caloric value Little generation impact.Especially characteristic fenced up with circle shown in Fig. 2 etc. makes the caloric value in high capacity type battery ES-E Increase than the caloric value in high performance type battery ES-P.Therefore, the caloric value of high capacity type battery ES-E compares high performance type Battery ES-P is big.
As described above, the characteristic of high capacity type battery ES-E is mutual with the characteristic of high performance type battery ES-P not Together, but ECU117 management each battery the upper limit management temperature be all same degree.Upper limit management temperature is to use battery When ceiling temperature, ECU117 restricted to the discharge and recharge of battery that temperature is managed more than the upper limit.Though it should be noted that So the caloric value of VCU107 is bigger than high capacity type battery ES-E, but upper limit management temperature also than high capacity type battery ES-E and Each upper limit management temperature of high performance type battery ES-P is set to height.
Next, to the high capacity type battery ES-E in electric vehicle, high performance type battery ES-P and VCU107 Configuration is illustrated with respective cooling.Fig. 3 is to represent high capacity type battery ES-E in electric vehicle, high performance type electric power storage The figure of the relation of the position of pond ES-P and VCU107 and the flowing of coolant.As shown in figure 3, in the inside of electric vehicle, Fig. 1 institutes High capacity type battery ES-E, the high performance type battery ES-P and VCU107 for showing using by the coolant as cooling medium by The mode cooled down according to the order of high capacity type battery ES-E, high performance type battery ES-P, VCU107 is configured.That is, exist On high capacity type battery ES-E, high performance type battery ES-P and VCU107, it is formed through pipeline and they is linked into cyclization The circulation road 119 of shape, direction of the coolant along Fig. 3 shown in the arrow of dotted line are flowed in the circulation road 119.
In the inside of electric vehicle, except high capacity type battery ES-E, high performance type battery ES-P and VCU107 it Outward, as shown in figure 3, being additionally provided with electric water pump (EWP) 121, radiator (RAD) 123, radiator being arranged on circulation road 119 Fan 125, temperature sensor 1271,127e, 1272, the ECU117 shown in 127p, Fig. 1.Electric water pump 121 produces cold for making But the pressure that liquid is circulated in circulation road 119.Radiator 123 is by the inflow air of vehicle front to following in circulation road 119 The coolant of ring is cooled down.Radiator fan 125 is carried out cold by coolant of the wind further to passing through in radiator 123 But.
Temperature T1 of the coolant before 1271 couples of cooling high capacity type battery ES-E of temperature sensor is detected.Table The signal of temperature T1 that temp. displaying function sensor 1271 is detected is conveyed to ECU117.Temperature sensor 127e is to high capacity type electric power storage Temperature Te of pond ES-E is detected.Represent that the signal of temperature Te that temperature sensor 127e is detected is conveyed to ECU117.Temperature Spend after sensor 1272 pairs cools down high capacity type battery ES-E and cool down the coolant before high performance type battery ES-P Temperature T2 detected.Represent that the signal of temperature T2 that temperature sensor 1272 is detected is conveyed to ECU117.TEMP Device 127p is detected to temperature Tp of high performance type battery ES-P.Represent temperature Tp that temperature sensor 127p is detected Signal is conveyed to ECU117.
The temperature that ECU117 is detected based on temperature sensor 127e, 1272,127p is controlling the drive of electric water pump 121 It is dynamic, thus adjust the quantity delivered of the coolant circulated in circulation road 119.In addition, ECU117 based on temperature sensor 1271, Thus the temperature that 127e, 127p are detected adjusts circulate in circulation road 119 cold controlling the driving of radiator fan 125 But the temperature of liquid.Hereinafter, with reference to Fig. 4, the control of electric water pump 121 and radiator fan 125 that ECU117 is carried out it is detailed Content is illustrated.Fig. 4 is the flow chart of the flow process of the cooling treatment for representing that ECU117 is carried out.
As shown in figure 4, ECU117 judges temperature Te of the high capacity type battery ES-E that temperature sensor 127e is detected And whether either one in temperature Tp of high performance type battery ES-P that detects of temperature sensor 127p is threshold value Tth Above (Te or Tp >=Tth) (step S101), if Te or Tp >=Tth, into step S103, if Te and Tp be ＜ Tth, return Step S101.In step s 103, ECU117 controls into driving electric water pump 121.It should be noted that as threshold value Tth, if Determine the upper limit management temperature or the temperature near which of high capacity type battery ES-E and high performance type battery ES-P.
Next, ECU117 judges temperature (temperature) T1 of the coolant before cooling high capacity type battery ES-E The whether temperature of the relatively low side in temperature Tp of temperature Te and high performance type battery ES-P than high capacity type battery ES-E Degree is high (T1 ＞ Te or Tp) (step S105), if T1 is ＞ Te or Tp, into step S107, if T1≤Te and Tp, returns step Rapid S105.In step s 107, ECU117 controls into driving radiator fan 125.
Next, ECU117 judge temperature Tp of high performance type battery ES-P be whether more than threshold value Tth (Tp >= Tth), and after cooling down high capacity type battery ES-E and cool down the temperature of coolant before high performance type battery ES-P (secondary temperature) T2 (T2 ＞ Tp) (step S109) whether high than temperature Tp of high performance type battery ES-P, if Tp >=Tth and T2 ＞ Tp, then into step S111, if Tp is ＜ Tth or T2≤Tp, return to step S109.In step S111, ECU117 controls Make, speedup is carried out to electric water pump 121 so that the quantity delivered of the time per unit of the coolant circulated in circulation road 119 Increase.
As described above, according to present embodiment, due to from the larger high capacity type battery ES-E of caloric value Rise and be preferentially cooled, therefore high capacity type battery ES-E is sufficiently cooled, in the high performance type battery ES- of downstream configuration P heated up by the heat by high capacity type battery ES-E after coolant cooling, but as caloric value is less, therefore filled Divide cooling.In such manner, it is possible to the cooling of the system for carrying out possessing the different multiple batteries of caloric value with optimal form.Need Bright, the upper limit management temperature of high capacity type battery ES-E and high performance type battery ES-P is all same degree, but high Capacity type battery ES-E and high performance type battery ES-P all balances are cooled well, therefore both sides remain suitably Temperature, the battery that can reduce an only side reach possibility as upper limit management temperature.
In addition, compared with high capacity type battery ES-E and high performance type battery ES-P, the caloric value of VCU107 is larger, But upper limit management temperature is also higher, even if therefore preferential cooling high capacity type battery ES-E and high performance type battery ES-P, Also VCU107 can be cooled down in the way of making VCU107 not reach upper limit management temperature.It should be noted that VCU107 The vicinity of high capacity type battery ES-E or high performance type battery ES-P is configured in, therefore in addition to two batteries, also VCU107 intensively can efficiently be cooled down.
In addition, the internal resistance of high capacity type battery ES-E is higher and caloric value is larger, but due to storing from high capacity type Battery ES-E rises preferential cooled, therefore, it is possible to carry out possessing the different multiple batteries of internal resistance with optimal form is The cooling of system.Further, since the energy-weight density of high capacity type battery ES-E is high and to export weight density low, thus with height Output type battery ES-P is compared and is usually used (discharge) that frequency is higher, and caloric value is larger, but due to from high capacity type battery ES-E rises and is preferentially cooled, therefore, it is possible to the cold of the system for possessing the different multiple batteries of characteristic is carried out with optimal form But.Further, since the desired value of the SOC of high capacity type battery ES-E is relatively low, therefore high capacity type battery ES-E is until SOC Continuous discharge till being reduced to the low target value.As a result, high capacity type battery ES-E caloric value increase, but due to from High capacity type battery ES-E rises and is preferentially cooled, therefore in view of because of the different of the desired value of SOC, caloric value is different On the basis of the difference of the occupation mode of each battery in multiple batteries, can carry out possessing this many with optimal form The cooling of the system of individual battery.In addition, the regeneration that cannot be charged to high performance type battery ES-P in regenerated electric power Amount of power is charged to high capacity type battery ES-E, but as the internal resistance of high capacity type battery ES-E is higher and fills It is poor that electricity receives characteristic, therefore caloric value is larger.But, it is cooled due to preferential from high capacity type battery ES-E, therefore On the basis of in view of difference of the charging by the occupation mode of each battery in the different multiple batteries of characteristic, can The cooling of the system for carrying out possessing this multiple battery with optimal form.In addition, quick charger 105 with high voltage to Gao Rong Amount type battery ES-E is charged, but the charging under high voltage is accompanied by larger heating in the battery.But, due to It is preferential cooled from high capacity type battery ES-E, therefore, it is possible to carry out possessing caloric value during charging with optimal form not The cooling of the system of same multiple batteries.
In addition, as illustrated in the flow diagram of fig. 4, it is cold to manage based on temperature T1 before cooling high capacity type battery ES-E But the temperature of liquid, temperature T2 and high performance type battery ES-P based on the coolant before cooling high performance type battery ES-P Temperature Tp relation adjusting the quantity delivered of coolant circulated in circulation road 119.Therefore, even if high performance type battery Temperature Tp of ES-P rises, by the temperature and quantity delivered that change coolant, it is also possible to suitably cool down high performance type battery ES-P.If the temperature T2 ratio for especially cooling down the coolant before high performance type battery ES-P is higher than threshold value Tth (with high power capacity The upper limit suitable value of management temperature of type battery ES-E and high performance type battery ES-P or the value near which) height output Temperature Tp of type battery ES-P is high, then high performance type battery ES-P is heated by coolant, but by entering to electric water pump 121 Row speedup and increase the quantity delivered of coolant, and reduce the heat that the coolant of unit quantity is transmitted by high capacity type battery ES-E Amount such that it is able to reduce temperature T2 of the coolant before cooling high performance type battery ES-P.Therefore, it is possible to pass through coolant To cool down the high performance type battery ES-P of the temperature higher than threshold value Tth.
It should be noted that the present invention is not limited to above-mentioned embodiment, suitably can carry out deforming, improve Deng.For example, the electric vehicle of described above for 1MOT types EV (Electrical Vehicle), but can be equipped with it is multiple The EV of dynamotor, can also be the HEV (Hybrid for being equipped with internal combustion engine and at least one dynamotor in the lump Electrical Vehicle) or PHEV (Plug-in Hybrid Electrical Vehicle).In addition, coolant is made The cooling medium illustrated for one can also be gas.
In addition, in the above description, coolant cooling to as if high capacity type battery ES-E, high performance type battery ES-P and VCU107, but it is also possible to replace high capacity type battery ES-E and high performance type battery ES-P and cool down caloric value not Two electric components of the same but upper limit management temperature for same degree.In this case, due to from caloric value it is big first Electric component rises and is preferentially cooled, therefore the first electric component is sufficiently cooled, and in downstream, the second of configuration is electrically pacified Although the cooling of coolant that piece installing is heated up by the heat by the first electric component, due to caloric value it is less, therefore quilt It is sufficiently cool.In such manner, it is possible to the cooling of the system for carrying out possessing the different multiple electric components of caloric value with optimal form.
In addition, as shown in figure 5, VCU207 can be also provided with high capacity type battery ES-E sides.By arranging two VCU, the voltage applied to dynamotor 11 and PDU13 are not fettered by high capacity type battery ES-E, therefore efficiency is improved.But It is, due to possessing two VCU, therefore it is required that there is high cooling performance.In addition, as described above, high capacity type battery ES-E with High performance type battery ES-P compares that to be usually used (discharge) frequency higher, therewith together, the VCU of high capacity type battery ES-E Operating frequency it is also high than the operating frequency of the VCU107 of high performance type battery ES-P.Therefore, as shown in fig. 6, by high power capacity The VCU207 of type battery ES-E is arranged on positions of the VCU107 than high performance type battery ES-P by upstream side.
